r tion and size so as to avoid the need of a large number of kdifferent patterns which cuts down the maintenance cost. l Afurther object of this invention isthe provision of a'refractory brick of such form that itniay beplaced with its major dimension extending in the same direction or at right angles and in either position Will effectively interlock and be held against lateral displacement. j v

A further object of this invention is the of a refractory structure of the character indicated in which broken joints can be made by piling in a vvall in a certain specified relation and at the same time have the members interlocked lagainst lateral displacement. f I

ln order that my invention may be better understood I have illustrated the same in preferred form ,in the accompanying drawings wherein.

Fig. 1 shows a longitudinal vertical scctional vieiv through the lire box of a locomotive such as is commonly used in oil burning practice and F ig. 2 shows a transverse sectional view taken on the line 4? of Fig. l. l f

Fig. 3 is an enlarged. pers aeetive view of one of the bricksl constructed in accordance with my invention showing how the upper and lower surfaces of the same are provided with corrugations or ribs and grooves extending diagonally across the face at an' angle of approximately 45.'

y Fig. t shows one brick superposed rupon another the tWo being placed at right langles to each other.

Fig. 5 is a sectional vievv taken on the line 5 5 of Fig. 4.

Fig. 6 shows one brick placed upon two otl1e1"s"with the klongitudinal axes in parallelism. y Fig. 7 is a section on theline 7-7 ot Fig.

`(Sand Fig. S is a partial sectional view simi lar' to that of Fig; 2 showing the arrangement of the bricks Where they are placed along Ian inclined pan or trough on the underside ofthe fireboxand present toward thefire arseries ofA corners orsteps While at the same time being interlocked by means of the angularly disposed irregularities.

Inconnection with this ligure it is to bc observed that by merely sliding the bricks Valong the corrugations or irregularities a greater or less distance they can be fitted to varying degrees of inclination of the Wall of the fire box. Y

Referring now more particularly toFig.v 1 it will be seen that I have therein indicated a lire box having the usual arrangement of Hue sheet l with flues 2, arch supporting tubes3,crown sheet t and rear inside sheet 5 there being a bottom plate 6 having fa hopper withA door 8 and burner opening at 9 and linedon its upper face with bricks made in accordance with my invention, the end or flash Wall at the rear marked -10 having the brick superposed in a common plane vertically While' thebrickslining the sides of the trough are arranged' as shown in Fig. 8 and Fig. 2, the successive superposed layers presentingv a seriesof steps upon the inside extending out a distance to correspond with the degree of inclination of the metal sheet l1. Y

At the corners the bricks are arranged as 'indicated in Figs. tand 5 in which position .because the corrugations or irregularities 'l2 are placed at 4.50 with respect to edges of the brick, corresponding irregularities or corrugations Will. ntertit and hold the bricks against lateral displacement.`

rThe corrugations or irregularities are so disposed on the upper and lower surfaces of the bricks that when bricks are superposed upon each other asindicated in Figs. 6 and 7 With the propergrooves and projections interengaging they will rest preferably With the joints in staggered or broken relationY as showny plainly in Fig. 7. Y

It will also be observed that the irregularities or corrugations should be placed on opposite faces `of the bricks with the'point axis of the bricks.

I have illustrated my invention in conneck tion with the refractory lining of a locomotive iirebox where, on account of its adaptability, tlie brick will be especially useful owing to the irregularitykof the surface to` be lined. It will be understood however that the use of my invention is not limited to locomotives as it is evident that bricks constructedL in accordance with my invention can be used as building blocks or in refractory linings of stationary furnaces with equal success.

Having thus described my inventionwliat I claim is tlie following: y

l. A block provided on opposite faces with corrugat-ions disposed at an angle of 45 to the longitudinal axis of the block. said corrugations extending` in one direction across the entire faces of the block.

2, A block provided on opposite faces with complementary corrugations disposed at anangle of 450 to the longitudinal axis of the block, said corrugations extending in one direction across the entire faces of the block.

3. A block provided on opposite faces with complementary parallel corrugations disposed at a substantial angle with respect to both the longitudinal and transverse axes 0f the block and extending in one direction across the entire faces of the block.

ntestimony whereof, I have hereunto signed my naine. K
